As Promised...drumroll please... Update to full time scrappin'

If I may: I have a sales/recruiting background so I can present my business well. Since you mentioned: I struggle with my own self-confidence issues when it comes to interacting with potential customers, might I recommend a little sales/self confidence training. It's easy, just go to the Library and pick up 1 book and read it (just get one at a time). Don't go crazy reading this all in one day, just read a chapter and use the info on your next cold call. You can start with someone like Zig Ziggler or Dale Carnegie. Also, less is more. When you are speaking to potential clients, stop talking and let them talk and then listen. Write things down that they tell you, if that will help you. Smile!!!
A couple of months ago, on my lunch hour, I walked into 3 office buildings just up the street from where I worked. I spoke to maybe 7 people. One of them gave my flyer to their IT Director. Over the last week I have obtained, 4 Pickup truck loads and 1 trailer load of e-waste. That was the only marketing I have ever done and it produced $$$. And it is one of the largest companies here. I'm now trying to get them to allow me to use their logo on my flyer. That would be a awesome.
Start reading/training, present yourself professionally, listen, less is more,,,,,,and you will do fine.
PM me and I will share my phone number and you can call me to discuss.
